What it is

Free AI Video Upscaler is a browser-based tool for enlarging videos and images with AI, available on the web and Android. Video processing runs locally on the device through WebGPU, with WebGL as a fallback, and the project is based on WebSR with open-source algorithms including Anime4K and RealESRGAN. Video output can reach 4K, while image output can typically reach 8K depending on the device. Enhancement modes are Fast, Balanced, Quality, Ultra, Anime4K, and RealESRGAN. The free plan costs nothing, is billed forever, requires no signup, and has no watermark. MP4, WebM, and other browser-playable video formats are accepted. The FAQ says there are no length or file-size limits, although large files may process slowly. Videos cannot be processed simultaneously. Supported browsers include current listed versions of Chrome, Edge, Opera, Safari, and Firefox with WebCodecs API.
